Costs
Corridors can be expensive to plan out and put into action. For example, Daniel Simberloff et al. states that “a bridge that would maintain a riparian corridor costs about 13 times as much per lane-mile as would a road that would sever the corridor.” He also states that maintenance of a corridor would be much more costly than refuges for endangered species. It would simply be easier to move animals between refuges than to buy land, install a corridor, and maintain it. However, where the goal is not just to preserve a few large animal species but to protect biodiversity among all plants and animals, then habitat corridors may be the only option. Corridors are going to be expensive to implement no matter what, but it does depend on the type, location, and size, which can all vary to a great degree. With the lack of field data on the effectiveness, many agencies are not willing to consider putting in corridors.

Famous quotes containing the word costs:
“That which costs little is less valued.”
—Miguel De Cervantes (1547–1616)
“It is commonly said by farmers, that a good pear or apple costs no more time or pains to rear, than a poor one; so I would have no work of art, no speech, or action, or thought, or friend, but the best.”
—Ralph Waldo Emerson (1803–1882)
“Pride can go without domestics, without fine clothes, can live in a house with two rooms, can eat potato, purslain, beans, lyed corn, can work on the soil, can travel afoot, can talk with poor men, or sit silent well contented with fine saloons. But vanity costs money, labor, horses, men, women, health and peace, and is still nothing at last; a long way leading nowhere.—Only one drawback; proud people are intolerably selfish, and the vain are gentle and giving.”
—Ralph Waldo Emerson (1803–1882)
